PXIE-5663 Datasheet, PDF (7/8 Pages) National Instruments Corporation – Vector Signal Analyzer

Vector Signal Analyzer
Error Vector Magnitude (EVM) and Modulation
Error Ratio (MER)
(Nominal)
Data length in the following three tables is 1,250 symbols pseudorandom bit
sequence (PRBS) at -30 dBm power level. These results were obtained using the
NI 5663 onboard clock (the NI 5652 LO source onboard clock) and do not include
software equalization using the NI Modulation Toolkit. Results are the composite
effect of both an NI 5663 vector signal analyzer and an NI 5673 RF vector
signal generator.
